A growing number of wildlife-vehicle collisions on Alberta’s highways have long been a concern for conservationists, motorists, and government officials alike. Recent initiatives focusing on the construction of wildlife overpasses and underpasses are now starting to show measurable results. These engineered crossings, designed to help animals traverse busy roads safely, target species such as deer, bears, and cougars that are most vulnerable to traffic accidents. Their success marks a pivotal change in the province’s approach to road safety and wildlife conservation.
In 2022, Alberta Transportation and municipal wildlife agencies collaborated to build several new wildlife crossings along Highway 1, near Banff National Park, a hotspot for animal-vehicle incidents. According to data released in early 2024, collisions between vehicles and large mammals have dropped by approximately 80% in areas equipped with these structures. These promising statistics underline the effectiveness of purpose-built infrastructure in reducing harm to both people and animals.
The wildlife crossings themselves are feats of modern engineering. Overpasses, often designed to look like natural extensions of the landscape, are covered with local vegetation to encourage cautious species, such as bears and cougars, to use them. Underpasses, on the other hand, offer a less exposed route beneath the busy roadways, appealing especially to deer and smaller mammals. Fencing along the highways funnels animals towards these safe passages, reducing random attempts to cross dangerously at ground level.
According to Dr. Elaine Wainwright, a leading wildlife biologist with the University of Calgary, these crossings do much more than prevent fatal accidents. “They support ecosystem connectivity, allowing creatures to access food, mates, and seasonal habitats without being cut off by human infrastructure,” she explains. This restored movement is vital for maintaining healthy populations, genetic diversity, and resilience among Alberta’s wildlife.
Local residents and drivers have generally expressed support for the project, particularly those who have witnessed or narrowly avoided serious accidents on these highways. Calgarian truck driver Joel Peterson recalls, “Before the overpass went in, I hit a deer late one night. It was awful for both me and the animal. Since then, I’ve noticed so many less animals on the road.” Such testimony reflects a shift in public perception toward valuing engineered solutions for coexistence with nature.
Alberta’s approach has also drawn international attention, with highway planners in the United States and Europe citing the province as a model for similar projects. Natalie Steadman, an advisor with the International Union for Conservation of Nature (IUCN), notes, "Alberta’s commitment to integrating science into infrastructure planning sets an example for balancing ecological needs and human transportation demands." The province’s willingness to invest in long-term solutions has become a blueprint for regions facing similar wildlife challenges.
Construction and maintenance of these crossings come with significant costs, but research indicates these investments may pay for themselves over time. A 2023 report by the Insurance Bureau of Canada found that wildlife-vehicle collisions cost Albertans over $150 million annually in vehicle repairs, medical expenses, and insurance claims. With collision rates dropping sharply near crossings, long-term economic benefits are expected to offset initial expenditures.
More crossings are planned as part of Alberta’s ongoing transportation infrastructure strategy. Officials say that locations for new overpasses and underpasses are being decided based on wildlife movement data, using GPS tracking collars on animals to identify high-traffic areas. This data-driven approach ensures resources are allocated where they’ll have the greatest impact, both for animal safety and the prevention of further accidents involving motorists.
Despite early success, conservation groups caution that more work must be done. “These crossings are effective, but their benefits are limited if not maintained properly, and if fencing is breached, animals can again wander onto roads,” warns Lisa Matthews of the Alberta Conservation Association. She also highlights the importance of education campaigns to inform drivers about ongoing wildlife activity, especially during migration seasons when traffic from wild animals spikes.
Looking ahead, Alberta’s wildlife crossings represent a promising intersection of technology, ecology, and public safety. By combining research, engineering, and community support, the province is taking proactive steps to address the challenges of living alongside nature. While challenges remain, the early results offer hope that with continued investment and innovation, both animals and humans can navigate their shared landscapes more safely and sustainably.
